Natalia Connolly and Kevin Madura of AlixPartners pointed Claude Code at a real post-merger procurement analysis: hundreds of vendors and more than 40,000 contracts. The first answers looked complete, but one total was off by about $800,000 and a key renewal deadline was a month late. They walk through why: long contracts that silently failed to process, amendments that weren't linked to their parent contracts, and rate tables split across pages. They explain how a five-stage pipeline that structures the data first, plus custom tools with built-in business rules, made every answer traceable to its source. They also share lessons on clear access errors, de-duplicating savings found by parallel agents, and giving the agent context about what the business is already doing.
